概括
治疗先进的HER2正常乳腺癌的第一线capecitabine单疗法显示,平均整体存活时间为16.4个月. 雌激素受体阳性患者的存活时间较长,但capecitabine的效果似乎不如较新的治疗方法.
科学领域:
- 在瘤学瘤学.
- 临床药理学 临床药理学
- 流行病学 流行病学
背景情况:
- 皮他是先进乳腺癌的第一线选择.
- 在这种情况下,关于capecitabine有效性的现实数据是有限的.
- 人体表皮生长因子受体 (HER2) -正常的晚期乳腺癌需要进一步的疗效评估.
研究的目的:
- 评估卡佩奇他单一治疗在晚期HER2-正常乳腺癌中的现实结果.
- 评估总生存率 (OS) 和无进展生存率 (PFS) 作为主要终点.
- 根据患者特征分析治疗疗效.
主要方法:
- 丹麦乳腺癌组织 (DBCG) 数据库的回顾性分析.
- 包括接受一线卡佩奇他单一治疗的HER2-正常晚期乳腺癌女性患者 (2010-2020年).
- 对OS和PFS的评估.
主要成果:
- 包括494名患者;中位数的生存期为16.4个月,中位数的PFS为6.0个月.
- 雌激素受体 (ER) 阳性患者的寿命明显更长 (22.8个月 vs 10.5个月) 和PFS (7.4个月 vs 4.9个月).
- 年龄影响PFS:患者<45岁有4.1个月,45-70岁有5.7个月,70岁以上有7.2个月.
结论:
- 在HER2-正常的晚期乳腺癌中,单独治疗capecitabine的疗效与现有的回顾性数据一致.
- 然而,与当代和较新的化疗或向疗法相比,它的有效性似乎较差.
- 对这一患者群体进行最佳第一线治疗的进一步研究是有必要的.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
